To all whom t may concern.' f

Be it known that I, GnAN'rE.-A-LLEMAN,` a citizen of the United States', yresiding at Shoemakersvilldin the county ofBerks and State of Pennsylvania.,

tain new and useful improvements in Dredging-Machines, of which the following is a specification. f I

My invention relates particularly yto dredging machines, and is especially applicable to machines designed-for*reclaiming fugitive coal which iswashed down' from the mining districts the bottom of rivers and streams.

The principal objects ofmy'finven'tion are,iv

to provide a dredgingwmachine having its parts so yinterchangeable asy "to 'permit of great flexibilityy y means` for agitating the coal deposits adjacent to the mouth of the suction-pipe; to provide means for `quickly" reversingthe,k said agitating meaii's;`-and togprorv vide means for preventing sticks and other motion of debris from entering ,the suction pipe."y

Other objects of my invention are, tofpro! r vide a dredging machine having its"'-p`arts so constructedas to preventclogging, due' to any solid particles collecting between relatively inovablesurfaces; and to pro'videa rotary pump haviiigits chamber increasing i in area toward its outlet.`` My agitator', and includesmeans `for preventing a slackening of' said belt adjacentto the mouth oi' the suction pipey My invention arrangement hereinafter more deiinitelydescribed. ln the accompanying Adrawiugs,'Figure 1 is a side elevational viewota iloatfcarrying dredging machinery constructed in accordance with iiiyinvention, the parts' being shown in their operative position; Fig".` -2is' a view similar n suction pipe raised to its inoperative posi-L tion; Fig. 3 is tion as shown mentary plan view of the intake end ofthe suction pipe; Fig. 5 is a central vertical lontalren onthe rline a transverse verti- 5-5 in Fig. 4;; Fig. 6 is have invented oerand is deposited yupon p p swivel ring,

invention coniprehend's an endless belt further includes allir of the" ifarious novel ,features of; construction and ,thesprocket-304m proclret 30 is mounted on the shaft I to Fig. 1, but showing the' a plan view oftheconstruc' in Fig. 2; Fig. l is a frag' the engine'2, connected through thecontroll-k ling clutch 3, having the operating vlever 4l, by the chainbelt 5 with the shaft 'of the pump 7, said shaft' being supported in the bearing block 8.'

he f pump Z i`s` connected through the or collar 9 y movable suction pipe l0, which is Vsupported withl the` relatively in the bearing-block l2 and eXtendslatera-lly i from,y said pump and turnsy in alongsweeping bend 13 int'o'longitudinal relationto the side of the y tance therefrom, ^so `as to'V cally the bed"r ofthe stream,

The Vv'findlass-comprises the shaft 2l which is mesh withthe pinion 23, to which the op'ei'atinghandle 2e' may be attached. *"*f he `frame l5 carries depending supports float and ata suitable dise,` be swung vertify and thereby'present its intake end' yat as best shown. in`

Y Y f Y.

The gear 39 is directly. in mesh with the gear 45, ywhich Yis mounted on the shaft 6 and arranged to rotate therewith, while the gear 40 is connected through the idler Thus it will be seen -that Copies of this Ypatent maybe ottained'forpve entseach, by addressing thi-I n f 'd Washngtongl). C.

the upper .portion for a considerable distance over y is kprovided to 46 with thegear 47, which is mountedon the shaft 6 and arranged to rotate therewith.

ythe gears 39 and 40 are rotated in opposite directions, and there fore when the clutch 43 v i one or the other, the shaft 36 will be caused to rotate in accordance therewith, so that the agitating belt 27 may be driven in either direction and quickly reversed. y Asbest shown in Figs.f4 and 5, the intake end of the pipe 10 is provided with al bear ing frame 49'for the shaft 50 of the pulleys y 29,"and comprises side plates whose forward ends. 51 diverge toward the respectiyepulfV prevent pebbles or'other debris .from

1. In a dredging machine, the combination with a suction pipe having opening, of a pump, ya swivel connection bemeans for raising and lowering the intake end of said pipe, a frame at the intake end of said pipe,

Vpulleys mounted on said frame, a sprocket a chain belt having a carried by s aid sprocket and pulleys, a guide for supporting said belt intermediateof said sprocket and pulleys, supported on said frame at one end and restmay be carried thereby. d y

2. In a dredging machine, tion lwith a suction pipe the .combinaspacedy transversescrapers mounted torotate over said opening, frames adjacent to the intake end of said pipe, Y plates whose .y free ends relatively diverge, and belt-supporting 'pulleys spaced from the body of saidplates and in contact with said diverging ends.

and an apron pivotally shedA any ydebris which and having side` that the inta-ke an intake soV v having an intake opening provided Awith a removable .shield or extension, of a chain belt having suitably` rotatably i ln witness whereof, l have hereunto set my hand April, A. D., 1914. y Y
